ON: The classification of Pleurothallidinae subtribe (one of the biggest) is one of the most complex and many scientists consecrated their time in studying it and suggesting many changes.
We have a very interesting and confusing situation in Pleurothallidinae, common in many others orchids group: the recognition of the genera was based on the floral morphology, but it isn’t indicative of relationships among them, but the floral adaptations with their pollinators.
Now we have a system where the genera are recognized as monophyletic groups (a genus is integrated by all species with the same evolutionary history and the same ancestor throughout the time) and the species that not belong to this group, should be placed in other genus, its respective monophyletic group.

 Project description   (Site not responding. Last check: 2007-10-08)
Luer (1985) stated that the taxonomy of Pleurothallidinae was fraught with problems and unnatural groups have been recognized as unambiguous synapomorphies have eluded researchers.
Their hypothesis that subtribe Pleurothallidinae has undergone a unilinear reduction in the number of pollinia was not supported by their study.
We feel that dense taxon sampling of Pleurothallidinae is required not only to provide phylogenetic resolution, but also to evaluate the distribution of potentially homoplastic morphological characters mapped onto a relatively complete molecular tree, to reveal biogeographic patterns of cladogenesis, and to produce a stable classification.

 Pleurothallidinae (Orchidaceae)
Orchids of the subtribe Pleurothallidinae are among the most popular of the "species" orchids — naturally occurring species of plants, rather than the (usually) more showy hybrids — grown by amateurs.
Like most epiphytes, Pleurothallidinae plants are very sensitive to any build-up of mineral salts in the potting medium.

Orchids are found all around the world except in the deserts, although are found at the sea-level, they are more numerous at higher altitudes.
Some orchid species are among the world's smallest flowering plant like Eurystyles or many Pleurothallidinae plants.
Others can reach a 4m height like Selenipedium that grow in tropical America or Grammatophyllum papuanum from Papua-New Guinea.

The genus was created in 1978 by Dr Carlyl Luer by extracting certain species with hairy flowers and curious lips from the genus Masdevallia, thus draculas are similar to the more commonly grown masdevallias, but differ in certain aspects of leaf structure, and in the flowers.
